16 Stamina has been fully removed and it has been turned to a DPS-chest, turning its low amount of Strength, 11 to be exact, to a whopping +54 Attack Power - most likely the reason for the change was to make it, in general, a more useful chestpiece, as at level 58 you can enter the Outlands, and tanking before 60s as a druid isn't very common. With the update it will very likely last to the very zone of Outlands, but the quests in Hellfire Peninsula will quickly upgrade this magnificent chestpiece.

- wowwiki hasn't been updated with the new stats, so I assume it was a recent patch which changed this, my suspicion is patch 3.1 which updated a couple of other items aswell, someone who can confirm is more than welcome to comment a reply to this -
